I am installing an overflow on a new bathtub. The overflow is very similar to the one pictured. The washer supplied is not tapered to match the slope of the tub wall, but it is very thick and spongy. But the washer is so thick that there is absolutely nothing holding the overflow elbow centered on the overflow hole (the ABS plastic "lip" on the elbow does not extend as far as the washer). That is, the one screw that holds the trim plate on will pass through the overflow hole in the tub, but not necessarily in the center.
The trim cover is metal and like the one shown here. I also wonder if the metal edge of this trim cover will bite into the acrylic tub?
1) Are my assumptions about the overflow correct - that there is nothing to center it and that I have to center it by eye as I tighten the trim screw? Any suggestions how to do this.
2) Is there a better choice for an overflow kit? I don't mind making the ABS connections myself and I have the drain "shoe elbow".
Adding one thing: We are using a drain stopper that is operated at the drain, so there is no stopper on/off mechanism to worry about.
